Wi-Fi is ubiquitous, and a great way to connect an application to the internet. We know wireless is a crucially important checkbox for many products, and we know how difficult integrating Wi-Fi can be. The new WGM110 Wi-Fi Expansion Kit can help.
The WGM110 Wi-Fi Expansion Kit is an add-on board that can plug into the EFM32PG1, EFM32PG12 and EFM32GG11 starter-kits (STKS) to enable Wi-Fi connectivity through the attached WGM110 Module. In addition, the software demo utilizes Micrium OS to ensure easy development.
The pre-certified WGM110 Wi-Fi module has the antenna and wireless stacks already integrated, so you can skip complex design and move straight to adding value in your core applications. Wi-Fi gives direct IP connectivity, and allows for greater through-put than similar connectivity technologies, making downloading, uploading, and data sharing easier and faster. With the quick addition of Wi-Fi through the WGM110 Expansion Kit, you can bypass the costly certification and complex development processes and capitalize on quick time to market turnarounds.
Taking advantage of the WGM110 Wi-Fi Expansion Kit for the wireless component of your application means all the heavy lifting is taken care of. The connected EFM32 MCU can be focused on the application itself, without worrying about network timing or the complexities of a network protocol. The WGM110 Wi-Fi module offers a great combination of features and performance. The module’s features include an integrated web-server, a soft-access point with support for up to 5 clients, as well as security through WPA2 Enterprise/Personal. The WGM110 has a throughput of 2 MBit/s. The EFM32 MCUs include a wide range of options and functionality for low power operation, connectivity. With the new EFM32 Giant Gecko Series 1, options include QSPI, SDIO and Ethernet, as well as functionality for graphical displays, sensor operation and user interaction.
To make the demo for the kit simple and easily extensible, it has been built on top of Micrium OS. The Micrium OS allows an application to be split into multiple processes, and can give great insights into what is going on inside the application, through tools like uC Probe and Systemview.
The demo that comes along with the kit includes a web client that communicates with the device through images. In the web client, you can draw an image, and this will pop up on the display of the kit. This is done leveraging a simple cloud service, where the image is uploaded from the editor, and where the kit demo can poll for and download new images.
